Check Text (C-278678r1192830_chk)
Verify the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> Network Inspection System >> Turn on asynchronous inspection is set to "Enabled"; otherwise, this is a finding.
Procedure: Use the Windows Registry Editor to navigate to the following key:
HKLM\Software\Policies\Microsoft\Windows Defender\NIS
Criteria: If the value "AllowSwitchToAsyncInspection" is REG_DWORD = 1, this is not a finding.
If the value is 0, this is a finding.
